Acquired three-dimensional positional information is used to identify user created gesture(s), which gesture(s) are classified to determine appropriate input(s) to an associated electronic device or devices. Preferably at at least one instance of a time interval, the posture of a portion of a user is recognized, based at least one factor such as shape, position, orientation, velocity. Posture over each of the instance(s) is recognized as a combined gesture. Because acquired information is three-dimensional, two gestures may occur simultaneously.

The absorbent article provides a signal viewable from the top surface of the absorbent article which gives a perception of depth within the absorbent article. This creation of depth perception is accomplished by the use of at least two tones within a color and / or by the use of multiple tones and multiple colors operating together to create a perception of depth within the absorbent article.

A system and method for navigation within a surgical field are presented. In exemplary embodiments according to the present invention a micro-camera can be provided in a hand-held navigation probe tracked by a tracking system. This enables navigation within an operative scene by viewing real-time images from the viewpoint of the micro-camera within the navigation probe, which are overlaid with computer generated 3D graphics depicting structures of interest generated from pre-operative scans. Various transparency settings of the camera image and the superimposed 3D graphics can enhance the depth perception, and distances between a tip of the probe and any of the superimposed 3D structures along a virtual ray extending from the probe tip can be dynamically displayed in the combined image. In exemplary embodiments of the invention a virtual interface can be displayed adjacent to the combined image on a system display, thus facilitating interaction with various navigation related functions. In exemplary embodiments according to the present invention virtual reality systems can be used to plan surgical approaches with multi-modal CT and MRI data. This allows for generating 3D structures as well as marking ideal surgical paths. The system and method presented thus enable transfer of a surgical planning scenario to a real-time view of an actual surgical field, thus enhancing navigation.

Contact-less remote-sensing crack detection and / quantification methodologies are described, which are based on three-dimensional (3D) scene reconstruction, image processing, and pattern recognition. The systems and methodologies can utilize depth perception for detecting and / or quantifying cracks. These methodologies can provide the ability to analyze images captured from any distance and using any focal length or resolution. This adaptive feature may be especially useful for incorporation into mobile systems, such as unmanned aerial vehicles (UAV) or mobile autonomous or semi-autonomous robotic systems such as wheel-based or track-based radio controlled robots, as utilizing such structural inspection methods onto those mobile platforms may allow inaccessible regions to be properly inspected for cracks.

Methods and apparatuses for stereo-view visualization for control of perception of depth of a stereoscopic image generated by display device are provided. The method of stereo-view visualization for control of perception of depth of a stereoscopic image generated by display device, includes: estimating a disparity map for a source stereo-view image; adjusting depth perception parameters adjustment of depth perception of observed 3D content in TV-set; generating a modified stereo-view image based on the source stereo-view image, the adjusted depth perception parameters and the estimated disparity map; and post-processing the modified stereo-view image by spatial filtering of disocclusions of the modified stereo-view image.

The embodiments of the invention provide an image style migration model generation method and a mobile terminal. The image style migration model generation method includes the steps: constructing a style training data pair; establishing a neural network according to the structural sequence: an input layer, a preposition layer, at least one residual error characteristic construction layer, a postposition layer and an output layer in order; constructing a loss function based on the mean square error loss of a training original image and a style image and the mean square error of the depth perception feature; and according to the style training data pair and the loss function, training the neural network to generate an image style migration model. By means of the image style migration model generated by the image style migration model generation method, a high-fidelity image after style migration can be quickly obtained by inputting the image to be processed into the image style migrationmodel, without performing cumbersome iterative operations, so that the consumed time is short, and the processor has a light workload, and space distortion of the style migration image can be avoided.

A gaze contingent display technique for providing a human viewer with an enhanced three-dimensional experience not requiring stereoscopic viewing aids. Methods are shown which allow users to view plenoptic still images or plenoptic videos incorporating gaze-contingent refocusing operations in order to enhance spatial perception. Methods are also shown which allow the use of embedded markers in a plenoptic video feed signifying a change of scene incorporating initial depth plane settings for each such scene. Methods are also introduced which allow a novel mode of transitioning between different depth planes wherein the user's experience is optimized in such a way that these transitions trick the human eye into perceiving enhanced depth. This disclosure also introduces a system of a display device which comprises gaze-contingent refocusing capability in such a way that depth perception by the user is significantly enhanced compared to prior art. This disclosure comprises a nontransitory computer-readable medium on which are stored program instructions that, when executed by a processor, cause the processor to perform operations relating to timing the duration the user's gaze is fixated on each of a plurality of depth planes and making a refocusing operation contingent of a number of parameters.
